DAM-GATE-OPEBATILIVTG APPARATUS,

' AppIication fi ed March-20,1926." Seria1 No.96,1 89iZ I Thisinvention relates to mechanism'for 20; operated means for'conveying' the door units, individually or in small groups, to'andfrom "operable relation with respect 'to' the'tunnel operatingv and controlling large and heavy doorsor gates ofithe type .'more especially, employed as a barrier for the passage or tunnel offa dam to regulate the escape of the stream flow, or to confine water above the dam during theconstr'uction .of the same..

ji'lhis type of door, as heretofore constructed and operated has been difiicult'to remove from thetunnel opening by" reason of its largesize, weight and, more particularly, by reason of the necessity of overcomingjthe water pressure which'acts to hold the door against its seat; V I One ofthe objects of our inventionis to provide a door constituted of a plurality of superposed complementary units which may be regulated successively;

''Another object is to provide conveniently pe i v, a

further object isto provide devices for receivingand supporting the'units of a door when unemployed Other objectsand advantages of the inventionwill appear in the following specifi- CfltlOlL-f v a s I j'Tlie invention consists in the novel con struction, adaptation,- and combination of i parts hereinafter described'and clai ned In the accompanying drawings,"

front of the tunnel, we provide an elevator scopic connection with rods 31 whose lower against independent longitudinal movement ends are secured, as by means of flanged sockets 32 (Fig. 3), to the sill member 18, said rodsextending into the members serve to guide the latter in their up and down travel and also serve as axles about which the respective members are rotatable.

Near their upper ends said members are turnable and endwise movable in journal bearings 33 secured to the framework.v Said elevator members are also rotatable in journal bearing elements 34 (shown in detail in Fig. 6) of a yoke 35, which with the 'members 3O constitute the referred to elevator. The members 30 are each secured to the yoke as by means of a collar 36 (Fig. 6) rigidly secured, as by rivets 37 to the respective member, said collar being journaled in a yoke element 34: between its shoulders 38..

Topermit the members 30 being thus connected to the yoke, the bearing elements 34: of the latter are each formed of separable parts which are secured-together by coupling bolts 39. 1 At the extremity, prefer ably of each yoke, the same is provided with apertured ears 40, shown in Figs. 3 and 6,

- to which are engaged the ends of hoisting cables 41, one for each side of the elevator. For clearness only portions of cable ll are represented in Figs. 1 and 2, said cables being :wound about drums 42 (Fig. 1) mounted upon a shaft 43 which is rotatable: in journal boxes 44 secured to the upper portion of the framework. For winding said cables upon the drums, said shaft may be rotated by any suitable means, that shown, in the illustrated embodiment, cons sting of a manually. actuated machine 45 located upon the platform 22. Power is transmitted.

from the machine 15 through the medium of a sprocket chain, indicated by 16, to drive an intermediate shaft 1 7 from which, in turn, the drum shaft isdriven by a-sprocket chain, which is indicatedby 18.

For engaging the elevator to a door unit, each of the tubularmembers 30 is provided at .its lower end with a collar 49 having at diametrically opposite sides arms 50, see

Figs. 3 and 5, which are'adaptedflto pass.

I through the apertures 27 and-28 of the door units when the members .30 are regulated to have their arms 50 disposed longitudinally of a door unit, as shown in 'Flg. 5, but when themembers are rotated to. have the arms directed transversely, as shown in Fig. 3, the

same are engageable with the box element of a door unit to enable the latter to bec arried by the elevator. The elevator members 30 are turned to regulate the rotary positions of the unit engaging arms by any suitable means, the means shown consisting of operating arms 51 which are adj-ustably connected to the respective members as by means of clamp screws 52.

Included in the invention are means for releasably supporting the door units when brought thereto" by the above. explained elevator.

To such end we provide at the inner side of each of the guard timbers 14 a vertical tubular shaft 53 which is sleeved upon a rod, 541 which is journaled in a bearing of a bracket 55 (Fig. 3) secured to the respective guard timber 14.

Adjacent its upper end the shaft 53 is journaled in abearing 56 and above the. latter is provided with an operating arm 57 whereby the shaft 53 is rotated to swing an arm 58, which is provided upon the lower end of the shaft, into and from the aperture 29 provided therefor in the adjacent end of a door unit.

Gage device such as. 59, Fig. 3, may be secured to some part of the framework to indicate the maximum elevation of the door to'be entirely clear of the tunnel opening.

' Operation; The door is brought into its closed condition with respect tothe tunnel opening by successively piling the door units '23 one upon the otherabove the sill'18.

When it is desired to open the door the units 23 thereof are elevated singly or in groups of two or more according to the weight of the individual units and to the amount of-water pressure acting against the door units to bear the same against door jambs To raise the door'units, the elevator, consist ng of the yoke 35 and tubular members 30, is lowered to cause lts arm elements 50 to enter the boxes 25' of thelowermost unit of-a desired load thereofthat is to say, one or more of such units.

The arms. 50 are turned into positions suitable for passing through the apertures 27 and28 of the respective box elements by rotating the respective elevator members 30 through the .instrumentality of their operating arms 51. The elevator is then lowered by the operator allowing the shaft as to turn to effectthe uncoiling-of the elevator hoisting cables from the respective upon the drums, whereupon the elevator with its load of ,two units (in the present in:

stance), ascends to the elevation in which the apertures 28 of a door unit and thus low-' ered' with the elevator to pickup a second door, or so much of it as may be desired, is

raised into positions tobe supported by the supporting arms 58. 1 In the raisin /of the successive loads of door units, the load or loads previously elevated,'are raised by being borne upon" the elevator while the supporting armsare disciigagedfrom one door unit, after which the entire load then upon the elevator is elevated to have the lowermost unit of the load engaged by the supporting arms 58. I It may be mentioned that the door units when located in front of the tunnel opening are held to their'seats against the jambs 13 by an unbalanced pressure ofwater, thereby rendering the removal of the door extremely clifiiciilt unless the door is dividedinto units water pressure from .both sides thereby en- Which can be elevated singly or in groups as permitted in the present invention.
